Complete series of protections: current limiting, thermal shutdown and SOA control

The LM317 is a monolithic integrated circuits in a TO-220 packages intended for use as positive adjustable voltage regulators. Designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by means of only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.
